A source tells X17online exclusively that Samantha Ronson has been telling friends of hers and of Lindsay's that the two former lovers are back together.

As we reported last week, Samantha was visiting 4 - 5 times a week while Lohan was at UCLA Medical Center for rehab (despite reports claiming only family members could see patients). Now, word is Sam started falling for Lindsay again because of her vulnerability:

"Samantha always wanted to 'fix' Lindsay. Now that Lindsay has been legally and emotionally beat down, Sam is back to work trying to help. She's attracted to Lindsay when she's weak, for some reason. And apparently Lindsay never got over Sam so she was all for rekindling the relationship," a source tells X17online.

But is getting back together with her ex a healthy thing for Lindsay to do given the focus she needs to have on herself during this difficult time?
